When a THREAD MILL hole canned cycle is selected on the Cycles Data or Edit Cycle dialog, the following settings are available on the Edit Hole Operation dialog:
Hole Canned Cycle — This field displays the name of the hole canned cycle selected on the Cycles Data or Edit Cycle dialogs.
Style — Select the style for machining the hole:
- Bottom Up — Select so the tool starts at the bottom of the hole and threads up to the top of the hole.
- Top Down — Select so the tool starts at the top of the hole and threads to the bottom of the hole.
Thread Direction — Select the direction of the thread:
- Right Hand — Select so the thread is created in a right-hand direction (and the thread winds in a clockwise direction)..
- Left Hand — Select so the thread is created in a left-hand direction (and the thread winds in a counter-clockwise direction).
Hole Diameter (D) — This field displays the diameter of the hole. The value is taken from the Hole Diam field on the Cycles Data or Edit Cycle dialogs.
Tool Diameter (d) — This field displays the diameter of the tool. The value is taken from the Tool Data or Edit Tool dialogs.
Depth (H) — This field displays the depth of the hole. The value is taken from the Depth field on the Cycles Data or Edit Cycle dialogs.
Pitch (P) — Enter the distance between the teeth of the thread when drilling the hole. The default value of this option is calculated from the Threads Per Inch value (Inch units) or taken from the Pitch value (metric units) from the tool's properties in the Tool Data dialog.
Retract Type — This field displays the retract type. In a THREAD MILL hole canned cycle, the tool retracts completely out of the hole after each step.
Retract Motion — This field displays the retract motion. In a THREAD MILL hole canned cycle, the tool makes a rapid move when it retracts.
Output Hole Canned Cycle — This option is selected by default so the machining operation for the hole is output as a canned cycle in the NC Program file. If your postprocessor does not support all of the parameters for this canned cycle, deselect this option.
Thread Mill Options — Click to display the Thread Mill Options dialog, where you can control the start angle of the thread and whether a tapered thread is required.
